I am running the 486hp 460 from Ford Racing. This is a very docile engine on the street. Lumpy idle can be slowed all the way down to 400 rpm. It won't die. The added windage tray (usually good for 15 hp on the top end), the engine is in the 500hp range. Needless to say, lots of tire shredding power.
In my endless need to tinker, I'm wanting to switch to a hyd roller cam. I'm sure a proper profile would keep the street manors while bumping the midrange torque and high end hp. Maybe 550hp with same street manors. Sounds like what you are after also. Bad news, I haven't found the cam. Several people have pointed me to different suppliers of hyd roller cams for Ford 460's, but I haven't found anyone who has used them to report on their nature. With 11,000 miles in a year and a half, I'm not giving up my streetability.
